ICE/REMOVABLE GAP FOR CONTAINERS.

Specification of Letters Patent.

Patented Dec. 13, 1921.

Application filed October 27, 1919. Serial No. 333,711.

T 0 all whom it may concern:

Be it known that I, HARRY W. FULEN- 'WIDER, a citizen of the UnitedStates, residing at St. Louis, State of Missouri, have invented certainnew and useful Improvements in Irremovable Caps for Containers, of whichthe following is a specification, reference being had therein to theaccompanying drawing.

My invention relates to improvements in irremovable caps for containers,and has for its object to provide means, for securing threaded cap to acontainer, which acts as pivot upon which the cap may be bodily swung tofull open position relative to the filling opening of the container andwhich pivot is connected with the cap in such mannor as to not interferewith its rotation as required for its threading upon the cont iner.

in the drawings Figure l is a vertical sectional elevation of a deviceembodying invention, showing by dotted lines the cap as swung to openposition.

Fig. 2 is a plan of the device in open position.

As shown in the drawing, I employ as the body of my device the fitting 8which surrounds the iilling opening of the container, and is providedwith an externally threaded neck i, a perforated flange for securementto the container and a boss 5, on the inside of the neck, having a.boreor bearing 6 therein.

The cap 7 is provided with internally threaded flange 8, for engagementwith the neck 4 and with a circular way 9, defined by opposed circularribs 10 which form a restricted and continuous opening 11 for the way.

As shown, the top of the cap is provided with an opening 12 intersectingthe way 9, through which the headed pivot-pin 13 is inserted to aposition with its head 14: occupying the wa its stem 15 extendingthrough the restricted opening 11 and passed through the bearing 6, withits lower end projecting a distance beyond the hearing (as shown in Fig.1).

At a point on the stem 15, removed from the lower end of the bearing adistance, substantially equalling the height of the threaded neck i Isecure a fixed stop, such as the cotter, or split-key 16.

After the assemblage, as just recited, l insert a finish-filler 17 inthe opening 12.

It will be obvious that the cap may be freely rotated about the head ofthe pivot, as required in its threading and the pivot-stein rise andfall in the bearing 6, as the threading progresses and that when the capis moved to a plane above the neck it may be bodily swung, upon thepivot-pin to a full open position.

it is obvious that the described construction can be modified in variousways without departing from my invention, which invention broadlyresides in the provision of a permanent pivot connection between athreaded cap and a container fitting, which in no wise interferes withthe free threading or unthreading of the caps, whereby loss of the capis prevented by theft or otherwise.

Having thus described my invention, what I claim as new and desire tohave secured to me by the grant of Letters Patent, is

1. The combination with a threaded container fitting having a bearingand a threaded cap having a circular way, a pivot-pin having a headoccupying said Way and extended through said bearing and provided with afixed stop to prevent its withdrawal from the bearing.

2. In a device of the class described a container fitting having athreaded neck, and a bearing, a pivot-pin axially and vertically movablein the bearing and provided with a fixed stop at each end, and athreaded cap having an annular way for engagement with one of the stepsof the pivot-pin in a manner to permit the cap being rotated about thefitting and the cap swung to open position relative to the fitting.

In testimony whereof I hereunto affix my signature.

HARRY W. FULENWIDER.
